Usage

You can run the bot on your Raspberry Pi home server or free Heroku dyno.

Clone this repository:

git clone https://github.com/xDWart/mqtg-bot

Message @BotFather /newbot command to create a bot and get his HTTP API access token.

Environment variables

• TELEGRAM_BOT_TOKEN - bot HTTP API access token, required
• DATABASE_URL - Postgres connection string in the following format: postgres://user:password@host:port/db
• SQLITE_PATH - path to SQLite database
• MQTT_CLIENT_ID - Client ID to be used. Required for VerneMQ.

Notes:

1. Only TELEGRAM_BOT_TOKEN env is required
2. If DATABASE_URL env is omitted, or a Postgres connection error occurred, SQLite will be used
3. If SQLITE_PATH env is omitted, mqtg.db will be used by default as a SQLite database
4. You can create the .env file in the root of the project and insert your key/value environment variable pairs in the following format of KEY=VALUE

Local running

You can run mqtg-bot with environment variables:

TELEGRAM_BOT_TOKEN=... go run main.go

or if you've already created the .env file:

go run main.go

Running in Docker container

docker run -e TELEGRAM_BOT_TOKEN=... -e DATABASE_URL=... --network=host owart/mqtg-bot

Heroku running

You will need Heroku CLI

# login into Heroku
heroku login

# create a new app
heroku create *YOUR_APP_NAME*

# add your new app into git remotes
heroku git:remote -a *YOUR_APP_NAME*

# add TELEGRAM_BOT_TOKEN environment
heroku config:set TELEGRAM_BOT_TOKEN=*BOT_ACCESS_TOKEN*

# set version of Go
heroku config:set GOVERSION=go1.15

# attach Postgres add-on
heroku addons:create heroku-postgresql:hobby-dev

# push master branch to Heroku
git push heroku master

# scale up your app
heroku ps:scale worker=1

Then just message /start to your bot and follow the instructions to configure it.

Try bot

@mqtg_bot Message /start to him and configure connection to your MQTT broker.
